Updates a message. There's a difference between the patch and update methods. The patch method uses a patch request while the update method uses a put request. We recommend using the patch method. For an example, see Update a message.
Where {space} is the ID of the space where the message is posted and {message} is a system-assigned ID for the message. For example, spaces/AAAAAAAAAAA/messages/BBBBBBBBBBB.BBBBBBBBBBB.
If you set a custom ID when you create a message, you can use this ID to specify the message in a request by replacing {message} with the value from the clientAssignedMessageId field. For example, spaces/AAAAAAAAAAA/messages/client-custom-name. For details, see Name a message.
quotedMessageMetadata (Only allows removal of the quoted message.)
allowMissing
boolean
Optional. If true and the message isn't found, a new message is created and updateMask is ignored. The specified message ID must be client-assigned or the request fails.
